Abstract

Refinery Development Master Plan (RDMP) is a facility development project to increase the capacity of oil refineries, one of which is by building Pipe Rack. When making Pipe Rack with steel structure, time estimation is needed so that the fabrication process flow can run according to the planned time. One of the fabrication processes is the process of cutting profile steel using a Bandsaw machine. The estimated time of cutting profiled steel using a Bandsaw machine can be determined by the values that affect the cutting process so that initial data such as the value of cutting speed, feeding motion, sawblade type, and the type and dimensions of profiled steel to be cut are required. After knowing the initial data, the calculation of the estimated cutting time can be known with several equations. In the initial data, the feed motion is 5 mm / rotation with a sawblade length of 7600 mm and the dimensions of the profile steel to be cut are 400x200 mm. The machining time is 21.14 minutes with a cutting speed of 15,099.34 mm / minute. After obtaining the cutting speed value on the bandsaw machine, the estimated machining time of several variations of profile steel dimensions and different bandsaw machine feed motions can be determined. From the simulation results of several variation values of cutting speed and feeding motion, the longest cutting time is 21.28 minutes with a cutting speed of 15000 mm/minute and 47 minutes with a feeding motion of 2 mm/rotation. Meanwhile, the fastest cutting time is 10.64 minutes with a cutting speed of 30000 mm/min and 10.43 minutes with a feeding motion of 9 mm/rotation.

Abstract In an increasingly developing industrial era, companies must have consistency in their business activities, including fulfilling customer satisfaction. One of the factors that can provide satisfaction to customers is the suitability between expectations and the product provided, including the quality of the product. In order for product quality to be consistent, quality control must be carried out by the company. This study aims to identify defects that occur and provide recommendations for improvements to the production of camshafts at PT. Morita Tjokro Gearindo. Lean six sigma DMAIC concept is the method used in this study with five stages of systematic control. The data used in this research is the amount of production and the number of defective products in the period January-June 2022. These data are obtained from company reports and other data such as work systems, field conditions obtained through direct observation and interviews. From the analysis that has been done, it is known that there are still many defects above the company's tolerance limit of 0.5%. There are three types of defects that occur in camshaft production, namely burry, lip, and no chamfer journal. The results of calculating the company's sigma value obtained a value of 4.22, which means it is already above the Indonesian industry average. Based on the results of the Pareto diagram, the highest type of defect is burry with 75% caused by material, method and environmental factors. Proposed improvements based on the 5W + 1H analysis, namely having a manual book placed on the machine, making checksheets to ensure repeated checks, and having SOPs related to briefings before work and breaks to restore operator focus.Keywords: Distro, Apparel, Marketing, SWOT, QSPM Abstrak Pada masa industri yang semakin berkembang, perusahaan harus memiliki konsistensi dalam aktivitas bisnisnya, termasuk pada pemenuhan kepuasan pelanggan.

Abstract

PkM Tanjung Bungin Village, Karawang Regency is inhabited by 891 families or around 2,612 residents. Crowded places such as entertainment venues, sales of fishermen's catches and traditional markets are always busy with people from villages, sub-districts and even Bekasi Regency. Frequent interaction between the people of Tanjungbungin Village and people outside the village area because of the necessities of life that need to be met causes a large potential for traffic accidents on the connecting road. Apart from that, the unavailability of speed bumps around roads where there are potential accidents and their lack of self-sufficiency means that speed bumps increase the risk of high traffic accidents. There needs to be a program that can provide the right solution to immediately reduce the potential for traffic accidents. Making speed bump technology made from plastic independently among the community will be the right and effective solution. The plastic speed bump technology that had been made is based on research products and uses the same manufacturing method as that carried out in the research. The method that had been implemented is integration between PkM and student KKN activity programs by means of mentoring, training, and making speed bump technology made from plastic. The output of this community service activity was the creation and implementation of a speed bump made from plastic in Tanjungbungin Village, Pakisjaya District, Karawang Regency.

Abstract

Quality products, quality production processes are very important, from materials to products; However, problems and obstacles may develop in the production process. The aim of this research is to find out the problems that arise in the manufacturing process and find problems with the compressor which has an oil filter leak so that the air pressure consumed in the production process is reduced. FMEA is an organized approach to identifying and avoiding as many failure scenarios as possible. Data is processed by calculating the Risk Priority Number value in FMEA and determining the criticality of each failure mode. The assessment is based on the results of rounding the average weighting value for severity, occurrence and detection levels. The results of calculations using the FMEA technique show that the oil filter leak due to a broken ring creates a Risk Priority Number (RPN) value of 90. Overcoming the problem of oil filter leaks due to a broken ring requires preventive maintenance for 5000 hours.
